A view from the publisher… why we have commissioned Cambridge Primary Science

An enquiry-based, language-rich approach to learning with an international focus

Methodology and approach

Cambridge Primary Science is a flexible series that can be used to support a range

of teaching methods in different settings. We do this by offering a variety of ideas

for activities to support teaching and learning of each objective in the curriculum

framework, from which you can select those most suited to your learners.

In keeping with the Cambridge International Examinations curriculum framework,

Cambridge Primary Science strongly supports a science curriculum in which

enquiry is central. Support for the scientific enquiry learning objectives is

embedded across the series, with full guidance for teachers on how to develop

the required skills. Throughout, activities are suggested that will help learners to

discover and investigate scientific concepts for themselves in an engaging way.

Cambridge Primary Science is a truly international series, written for a global

audience. Exercises focussing on scientific vocabulary and suggestions for

classroom discussion are included throughout the series, thus supporting

development of language as well as subject knowledge. Examples from a

wide range of international settings are included and alternative activities are

suggested in case certain materials are hard to come by in your part of the world.

Page 5: Cambridge Primary Science Learners Book and Activity Book Samples

Key featuresIn our Learner’s Books, all required learning objectives are covered in an engaging visual layout and suggestions for hands-on activities encourage enquiry-led learning. The ‘Talk about it!’ features stimulates classroom discussion and the ‘Check your progress’ questions present assessment opportunities and help learners prepare for the Progression and Checkpoint Tests.

In the Activity Books, additional exercises for each topic may be completed in class or set as homework. The exercises help to consolidate understanding, apply knowledge in new situations and develop scientifi c enquiry skills. Core vocabulary is developed in a dedicated language activity for each unit in Stages 3 to 6.

The Teacher’s Resource Book with CD-ROM offers support for using all three components. The teaching ideas offer fl exibility with plenty of activity suggestions, as well as guidance on differentiation, assessment and using resources available online. Additionally, a collection of worksheets supports suggested activities. The resource offers fl exible delivery, with all content both in print and – in editable format – on the CD-ROM.

Introducing… Cambridge PrimaryCambridge Primary seriesIn addition to our market-leading titles for Cambridge Checkpoint, Cambridge O Level, Cambridge IGCSE® and Cambridge International AS and A Level, we will be publishing an exciting new series for the Cambridge Primary curriculum frameworks developed by Cambridge International Examinations for Stages 1-6 and for the Cambridge Primary English as a Second Language (ESL) curriculum framework developed by Cambridge English Language Assessment. This will complete the learners’ journey with Cambridge materials from Primary to Pre-University.

We are working with Cambridge International Examinations towards endorsement of the brand new suite of products for English, Mathematics and Science. Cambridge Global English will not go through the Cambridge endorsement process as it follows the curriculum framework developed by Cambridge English Language Assessment.

About the Cambridge Primary CurriculumCambridge Primary, typically for 5–11 year olds, gives schools a curriculum framework to develop skills, knowledge and understanding in younger learners. Cambridge Primary provides guidance for curriculum development and classroom teaching and learning. It enables teachers to assess children’s learning as they progress with Cambridge Primary Progression Tests. [Cambridge English Language Assessment tests for learners at the Cambridge Primary stage are: Cambridge English Starters, Movers and Flyers and Key English Test (KET) for schools].

About Cambridge Primary ScienceCambridge Primary Science fully covers the Cambridge Primary Science curriculum framework. The course offers plenty of teaching ideas to give flexibility, allowing teachers to select activities most appropriate to their classroom and learners.

An enquiry-based style of teaching and learning is stimulated, with the scientific enquiry objectives integrated throughout to encourage learning of these skills alongside the scientific concepts. The language level is carefully pitched to be accessible to EAL/ESL learners, with concepts illustrated through diagrams to allow visual understanding and learning. There is dedicated support for practising scientific language and vocabulary.

Comprehensive teaching support helps teachers to bring all elements of the course together in the classroom.

Words to learnpush pull force startget faster slow downdirection

Every day you push and pull many things. Push and pull are examples of a force.

Forces can start and stop things moving.They can also make things get faster,slow down or change direction.

Each team pushes with their feet.

Six children divide into two teams to have a tug of war. How are the children using pushing forces and pulling forces? What could they do so that they don’t get hurt?

6.5 Friction

Friction is a force that acts when two surfaces rub together. Some materials cause more friction than others.

Words to learnfriction gripsmoot h rough

When hands are rubbed together

friction acts between them.

You can go very fast down a slide.

There will be friction between your clothes and

the surface ofthe slide.

between them.

Rub your hands together. Feel them rubbing and getting warm.

There is friction between the bottom of your shoes and the � oor which helps your shoes to grip the � oor surface. This stops you from sliding.

The friction between the ball and the bat helps the ball to

change direction.

Ice is slippery. There is little friction between the puck

and the ice and so the puck slides easily when it is hit by

the player’s stick.

Friction can start and stop things moving.You need the friction between the � oor and your shoes to help you start walking.

If you roll something across a surface, friction will cause it to slow down. It will stop at some point. Friction also help things to change direction.

Activity 6.5You will need: a small trolley • a forcemeter • different types of surface

You can use a forcemeter to � nd out about friction. If there is more friction, you will need a bigger force to make something move.Plan an investigation.You will pull a trolley across different surfaces with a forcemeter.Predict which surface will produce the most friction. Try using a very smooth surface and a rough surface.How will you measure this? How will you record your results?When you have done the test, decide what your conclusion is.If you have time, test other surfaces.
